Related issues/PRs
The dependency on friendsofphp/php-cs-fixer was introduced in #3863.
Suggest a fix/enhancement
The PHP client uses a package called friendsofphp/php-cs-fixer version 1.12, which is incompatible with PHP 7.2 and above. To fix we could upgrade the friendsofphp/php-cs-fixer dependency to a newer version that supports PHP >= 7.2, e.g. v2.12.
